TREATING or LEATHER AND THE LIKE.

Application filediFebruar-y 8, 1926. Serial No. 86,894. I

This invention relates to a method of treating leather and moreparticularly to the method of making welts of diflerent characteristicsfrom a single strip of leather.

The invention contemplates the making of at least two welt pieces from asingle strip of leather. One of these welt pieces may be used as a calkor weather-proof welt, and the other welt iece may be used as a sandalwelt or for ot er purposes as will be apparent. The invention alsocontemplates the application of either the 'calk welt or the other weltor both to stitch-down shoes, and an im ortant feature .of the inventionis the PIOVlSlOIl of the calk welt to stitch-down shoes.

For a complete understanding of the invention,..reference is to.be hadtothe follow;- ing descri tion and to the accompanying drawings orming apart of this specification. 7

In the drawings: Fig. 1 is a perspective view of a fragment of a stripof leather treated in accordance with the present invention;

Fig. 2 is a view similar to Fig. 1 after one cutting operation has beenperformed;

Fig. 3 is a similar view illustrating another cutting operation F ig. 4is a perspective view of a fragment of the calk welt;

Fig. .5, isa perspective view of the thin welt piece;

Fig. 6 is a detail sectional view showing tlfie welt pieces applied to astitch-down s oe;

Fig. 7 is a fragmentary side view of a stitch-down shoe having a calkwelt.

Figs. 8 to 15 illustrate a modification.

Fig. 9 is a perspective view showing the cutting operation.

Fig. 10 is a perspective view showing the appearance of the strip afterthe removal of the central strip, the dotted line showing the cuttingline for the next operation.

Figs. 11 and 12 show the calk weltsformed from the strip shown by Fig.10.

Fig. 13 is a view of the central strip. removed from the piece shown byFi 9.

Fig. 14 is a fragmentary view of one of the calk welts with a pinkedrib. and

Fig. 15 is a view similar to Fig. 7 showing calk welts with the pinkedrib.

Referring to the drawings in detail, the

Fig. 4.

reference character 10 designates a strip of leather that is treated inaccordance with the present invention. This strip 10 is cutlongitudinally along the line indicated at 11 by a suitable cutter 12,as indicated on Fig. 2. The strip is also cut longitudinally from oneside to a mar inal line 13 by a suitable cutter 14, as indicatedby-Fig.3. The cutting operations result in forming from the single strip 10 twostrips 15 and 16. The strip16 may be used as a sandal welt or institch-down shoes, or for. other 1 to the .beadepieee 18, the. latter.isroll'ed by a press-roller and by a polishing roller. The finishedcalk welt piece is illustrated by In Fi s. 6' and. 7, is illustrated theappli-- cation 0' the calk welt to a stitch-down shoe. The upper 20 hasan outwardly down-turned portion 20. Over this down-turned portion 20 ispositioned the calk welt 15, as shown more clearly by Fig. 6, and a lineof stitching 21 secures the upper and the welt to the outer-sole 19. Thepiece 16 may, if desired, be placed between the downwardly turned upperportion 20 and the outer sole 19, as shown.

Referring to Figs. 8 to 15 which -illus-.

form a bead similar to the bee -piece 18. It

will thus be seen that by simple cutting and rolling operations, threewelt pieces of different characteristics may be formed from a singlepiece or strip of leather. Fig. 14 shows a calk welt having its headpinked or scalloped, making rough edges on the beaded edge, as indicatedat 28, and may be applied to a stitch-down shoe as shown by Fig. 15, 'ina manner similar to the application of the welt 15 with its bead-piece18, as shown byFig. 6.

In view of the above description, the

method, construction and utility lncident to the invention will bereadily understood, and it will be appreciated that bysimple cutting androlling operations welts of various characteristics may be formed from asingle strip of leather. The calk Welt pieces thus obtained maybeapplied to a stitch-down shoe as hereinbefore stated.

Having thus described the invention what is claimed and desired to besecured by Letters Patent of the United States is:

1. The method of treating a strip of leather or the like to form atleast one welt piece having characteristics of a caulk Welt comprisingthe step of removing from one strip of a strip substantially rectangularin cross section leaving a strip having two spaced longitudinallyextending marginal flanges, and the dividing of said flanged striplongitudinally to form two strips each having a marginal flange.
